That’s the biggest load of Catholic revisionism with absolutely NO evidence to support it I’ve ever heard. If you are getting your ideas of Foxe from the catholic church and their fellow agitators you are sadly misled.
Long before I was a Catholic, I was an honors graduate in history, with a specialty in military history and particularly the American and English Civil Wars. I read extensively in the 16th and 17th century English writers as part of my studies.
What moderns have a hard time understanding is that the Protestant/Catholic conflict in England (and hence our heritage in that regard) was first, political; second, cultural; and only third a religious conflict.
You also have to bear in mind the tradition of English polemics in the 16th and 17th centuries. I'm re-reading right now C.S. Lewis's admirable survey of 16th c. English literature (excluding drama) which is part of the Oxford History of English Literature series. He goes over in great detail the tradition of 'flyting' or abuse in print of ones political opponents. It's fair to say that exaggeration, personal attacks, scurrilous abuse, and outright lies were the order of the day. St. Thomas More, for example, was as guilty of this practice as anybody else when he launched on political opponents.
You cannot read Foxe (or for that matter any of the Catholic polemicists of the same time) as straight history. It will lead you far astray.
Foxe was a liar.
